A business-to-business professional sales representative is a person who actively and directly generates revenues for a company. Since people purchase emotionally and out of need, it is necessary to have individuals who can reassure the buyer that a sound logical purchase has been made. This individual is also a problem-solver for a business. The professional salesperson can help the business reach the company's profitability goals by working in coordination with a business to purchase the appropriate products or services. Skill development includes training in areas such as business, management, ethics, account/territory management, fundamentals of selling and managing client relations. To be a professional sales representative, a person must have other qualities. Some of these qualities include the ability to work well with others, the desire to be part of a team, and the ability to work with the unknown. In addition, the successful salesperson needs the following skills: critical thinking, decision-making, problem solving, questioning, diplomacy, and negotiation; as well as good oral and written communication skills.
